What causes nodules and polyps?
Nodules are most frequently caused by vocal abuse or misuse. Polyps may be caused by long-term vocal abuse but may also occur after a single, traumatic event to the vocal folds, such as yelling at a concert. Long-term cigarette smoking, hypothyroidism, and GERD may also cause polyp formation. Vocal abuse takes many forms and includes:
- allergies
- smoking
- tense muscles
- singing
- coaching
- cheerleading
- talking loudly
- drinking caffeine and alcohol (dries out the throat and vocal folds)
It has been noted that, for unknown reasons, vocal nodules occur more frequently in women between the ages of 20 and 50.
